3. using the increasing material manufacturing of lip supports object.
Fig. 1 schematically illustrates the typical method for manufacturing three-dimension object by continuous liquid interface manufacture (CLIP) And device.The device include with the micro mirror array such as laser light source of light engine 11 that operationally (operatively) is connect, or Scanning laser is projected through optical clear window 12 and enters polymerizable liquid 21.Carrier platform 15 and elevator and driving Sub-assembly 14 is operably connected, and the elevator and drive assembly 14 are operably connected together with light engine with controller 13 (in an alternate embodiment, window and light engine can be lowered far from fixed carrier platform).By being projected from light engine 11 The 3d object 31 (being rigid in this case) that is increased by the photopolymerization manufacture of polymerizable liquid 21 of light, wherein carrier is flat Platform and window are pushed into away from each other and the contact-segment 32 of 3d object 31 is attached on carrier platform.In the embodiment of illustration In, which is carried out by continuous liquid interface manufacture (being described above), thus in the object 31 and polymerizable liquid 21 of growth Between maintain continuous liquid interface 22, such as by maintaining the dead zone of non-polymeric liquid between window and polymerizable liquid (not Display) (or electrochemically, or by using immiscible liquid, or other means by carrying out CLIP as described above) It carries out.
Fig. 2 schematically illustrates the method and apparatus for manufacturing three-dimension object by CLIP, and is retouched as shown in figure 1 That states is essentially identical, except that the 3d object 31a increased is flexible.Notice the contact-segment 32a and carrier in object It is peeling-off between platform, cause gap to be formed.The gap can reduce the efficiency or speed of manufacturing process, and in some cases Under manufacturing process can be caused to fail.
Fig. 3 A-3B is similar to Fig. 2, except that by antistripping lip supports object 34b along contact-segment marginal portion At least part of 33b is added to object 31b to reduce removing seen in Figure 2.It notices in Fig. 2, the left side of object On removing it is more significant, overhang (overhang) of object is bigger at this.Therefore, in Fig. 3, lip supports object is added To the left side of object.It is not intended to be entangled in any specific theory of the invention, it is believed that building plate or " window " and the object increased Suction force between body leads to the anticlockwise torque of the attachment surface relative to component.That is, in some embodiment party (such as " pumping " or " reciprocal " operation mode, wherein the component increased is intermittently promoted towards window to promote to set in case Rouge flows into building region), the power of driving object towards window can have opposite effect, thus on another (right side) side of object Lip supports object can also have value.
As being seen more clearly in the enlarged view of Fig. 3 B, the average width dimension of lip supports object(w)Typically larger than The mean depth size of lip supports object(d)(e.g. twice, three times, five times or ten times big, or bigger), in order to manufacture It is removed it after object from object.Although lip supports object may be frangible in itself or can be with object point since its is relatively thin From, but close to the contact-segment marginal portion 33b of object in lip supports object, that is, right vertical dotted line intersection in figure 3b Point at may include score line, perforation etc..
Fig. 4 is another example for manufacturing object 31c by using the CLIP of antistripping antelabium 34c and then removing the antelabium Show.It also includes antistripping antelabium 34d that Fig. 5, which is similar to Fig. 4 using the exemplary object 31d of substitution,.In both embodiment party In case, manufactured object is usually substantially conical (for frustum) or gradually receives on cross-sectional area in shape Contracting, wherein lesser cross-sectional area is close to carrier platform.When with carrier platform (to the carrier platform to The carrier platform) initial contact (and attachment) area (32c, 32d) compare, manufactured object is in the manufacture phase Between when increasing at least once in total side surface area of contact window, which shows special value.
